MANLY fended off a sizzling Dragons comeback to win a thriller at WIN Jubilee - but the real losers might be NSW.

In a dramatic match, won 24-18 by the Sea Eagles, two certain NSW selections - winger Brett Morris and fullback Brett Stewart - were struck down by injury just four weeks out from Origin I on June 5 at ANZ Stadium.

Morris limped off with a left knee injury in the 14th minute and did not return. He will have scans today.

And to further worry NSW coach Laurie Daley, star fullback Stewart did not return for the second half after copping knees in the back. He also has hamstring issues.

More headaches for New South Wales State of Origin coach Laurie Daley as injuries force Blues backs Brett Morris and Brett Stewart off the field.

"We didn't want to risk him for the second half. We didn't think he was right to continue. He is a bit sore."

Asked about Morris, the Dragons' high-performance manager Andrew Gray said: "Brett has a twisting injury to his knee. He seems to have a bit of a sprain to the outside of his knee. At this stage, it doesn't seem too serious."

Manly led 18-0 after 21 minutes last night before Saints clicked into gear to score the next four tries.

The scores were locked at 18-18 deep into the second half before Sea Eagles winger Jorge Taufua - playing fullback in the place of Stewart - surged over for his eighth try in eight games this year.

Saints' comeback thrilled the home crowd but in the end they fell just short.
